Free online calculators
These calculators use Indian conventions throughout — rupee formatting with lakh and crore grouping, quarterly compounding for fixed deposits, current financial year tax slabs, and the standard GST rate bands. Every figure is calculated in your browser and nothing you enter is transmitted or saved. Treat them as planning estimates rather than official figures: they apply the standard formulas correctly, but real outcomes depend on fees, taxes, and terms specific to your bank, employer, or fund.
